Hint: Violet is the light colour with a short wavelength at the end of the visible spectrum, blue and ultraviolet (invisible). Isaac Newton named it one of the seven colours when dividing the colour of visible light in $1672$. Violet light is having a wavelength of approximately $380$ and $450$ nanometres. The colour’s name is obtained from the violet flower.
Complete step-by-step solution:
White light is colourless daylight. It comprises all the wavelengths of the visible spectrum at the same intensity. In easy terms, Electromagnetic radiation of all the frequencies in the visible spectrum, seeming white to the eye, is named white light.
Visible light comes up with infrared rays. The Sun releases visible light with its maximum power, although combining the entire emission power spectrum through all wavelengths reveals that the Sun emits somewhat more infrared than visible light.
Wavelength order:
$\text{red} \gt \text{orange} \gt \text{yellow} \gt \text{green} \gt \text{blue} \gt \text{indigo} \gt \text{violet}$
Violet is nearly associated with purple. In physics, violet is a spectral colour, and purple is the colour of different combinations of red and blue light, some of which humans look similar to violet. In general usage, both were introduced to colours between blue and red in hue, with violets near blue and purples closer to red. Similarly, in the classical painters' colour wheel, violet and purple are placed between blue and red, with violet closer to blue.
Violet is at one edge of the spectrum of light, between blue light, a higher wavelength, and UV light, which has a lower wavelength and is not apparent to humans. Violet includes light with a wavelength of approximately $380$ to $450$ nanometres. Violet objects usually appear dark because human vision is nearly insensitive to that wavelength.
Hence, Violet has the least wavelength.
Note: Visible light is the section of the electromagnetic spectrum that the human eye can detect. Visible light and its immediate near-infrared light are absorbed and released by electrons in atoms and molecules that travel from one to another energy level. A rainbow displays the optical or visible portion of the electromagnetic spectrum, whereas the infrared rays are placed just beyond the red side of the spectrum, and the ultraviolet rays exist beyond the violet end. However, unfortunately, these are not visible to the human eye.
